A Hero for the Atomic Age tells the story of how Heyerdahl organized an expedition to sail a balsa raft from Callao in Peru to the Tuamotu Islands in French Polynesia, and explains how he turned this physical crossing into an epic narrative that became imbued with a universal appeal. The book also addresses, for the first time, the problematic nature of Heyerdahl's theory that a white culture-bearing race had initiated all the world's great civilizations.
